The Candle Factory is producing a new candle. It has a radius of 3 inches and a height of 5 inches. What is the surface area of the candle? Use 3.14 for Pi. Round to the nearest whole cubic inch.

A cylinder with a radius of 3 inches and height of 5 inches.


Recall the formula S A = 2 pi r squared + 2 pi r h.

Answer:

87.92 square inches

Step-by-step explanation:

Surface area for cylinder is given by [tex]2\pi r^2 + 2\pi rh[/tex]

where r is the radius and h is the height of cylinder.

Given that candle is cylindrical in shape

Thus, Surface area for candle is calculated as given below\\

[tex]Surface / area \ for \ candle = 2\pi r^2 + 2\pi rh\\=>Surface / area \ for \ candle = 2*3.14*3^2 + 2*3.14*5\\=>Surface / area \ for \ candle = 2*3.14*3^2 + 2*3.14*5 = 56.52 + 31.4\\=>Surface / area \ for \ candle = 56.52 + 31.4 = 87.92[/tex]

Thus, total surface area for candle is 87.92 square inches.
